Thomson electromotive force $(e.m.f.)$

(C) The Thomson effect describes the phenomenon where an electromotive force is generated in a single homogeneous conductor when a temperature gradient exists between its two ends.This potential difference arises due to the redistribution of charge carriers caused by the temperature difference.Therefore,the electromotive force generated between the two ends of a single conductor at different temperatures is known as the Thomson electromotive force.
